A novel C–H functionalization method was successfully explored by a reductive three
molecule coupling of benzaldehydes and esters mediated by samarium and cuprous iodide;
thus, the diarylmethanol skeletons were afforded readily via an in situ esterification
in one-pot. Substrates including a variety of esters and different benzaldehydes were
investigated, and the desired products were readily obtained in moderate to good yields
under mild conditions.
